The Very Best Of Both Worlds

Camden 500 is the most astoundingly clean, linear, transparent preamp you’ve ever heard. But it also has “Mojo” - 2 discrete custom analogue saturation circuits that can be applied, exaggerated, and perhaps best of all - bypassed.

Clean, Precise, and Natural
Camden 500 provides the utmost clarity and detail when it is most required. Its custom 'Camden' topology achieves stunning low-noise and low-distortion performance: -129.8dB EIN (150ohm, unweighted) and THD+N as low as 0.0002%.  It also sets a new standard for frequency and phase linearity: ±0.7dB frequency response from 5Hz to 200kHz at max gain and <2° phase shift @ 50Hz – 20kHz. The sum result is the most natural sounding preamp you've ever heard.
Vintage, Warm, and Coloured
Camden 500 features "Mojo" - a custom analogue saturation circuit that transforms Camden 500 into the fattest, warmest, most colourful mic preamp in your arsenal. Designed to introduce harmonics and saturation effects that our favourite vintage gear produces, Mojo can be subtle, it can be exaggerated, but best of all it can be bypassed...

GAINCustom Topology

Featuring a custom *transformerless front-end topology with 68.5dB of gain, Camden 500 achieves groundbreaking performance in noise, distortion, frequency response, and phase shift throughout all 12 gain positions.

Tech Specs

Put simply, Camden 500 is one of the cleanest, most linear, and transparent preamps on the market. Our new ‘Camden’ preamp topology allows us to push the boundaries of Frequency response, phase shift, noise, and THD performance; and we have all the specs to back that up.

EIN: <-129.5dBu, 150 ohm source, unweighted
<-135.5dBu, Inputs common, unweighted

THD+N: <0.0004%, 1kHz, 35dB gain, 24dBu out

Phase Shift: <2.25°, 40dB gain, 20Hz to 20kHz
<4°, Max gain, 20Hz to 20kHz

Freq. Response:1dB, <5 Hz to >200 kHz, all gain settings

CMRR: >70dB, typ >85dB, 35dB Gain, 10-20kHz, 100mV Common mode

Camden 500 By The Numbers

By our calculations and measurements, Camden 500 is the cleanest and most transparent preamp on the market. In this video Elliott dives into the tech specs and explains how we've come to this conclusion by comparing some technical data and performance specs against some undisclosed competitors preamp's as well as showing off some audio examples of Camden 500 in action. This video is not for the faint-hearted...

Performance Graphs

Numbers on a spec sheet is one thing, however those numbers can change drastically depending on the frequency measured and preamp gain. Camden 500's technical performance excels not only at key gain positions, but also when the gain control is increased to its maximum. Many preamps can boast excellent performance at one gain setting but that performance can often fall apart once the gain is increased. Camden 500 retains minimal phase shift, frequency roll-off, and THD at all gain positions enabling you to get the best results out of ribbon and low-output dynamic mics without fear of losing performance as the gain is increased.

The below graphs display key performance metrics of Camden 500 measured at all gain positions and across the audible frequency range:

Camden 500 phase shift at all gain settings
Phase Shift: All Gain Settings
Less than 4° of phase shift at maximum gain between 20Hz-20kHz.
Camden500 THD+N ratio all gain settings
THD+N Ratio: All Gain Settings
THD+N is below 0.02% throughout all gain settings and frequencies.

Frequency Response: All Gain Settings
Less than 1dB frequency roll-off between 5Hz-200kHz at maximum gain.

Mojo Analogue Saturation

To compliment the clean front-end of the Camden 500, we built a brand-new type of saturation circuit consisting of an array of filters and discrete second and third order harmonic generators that allow precise emulation of the saturation and frequency reinforcement behaviours of vintage equipment. Mojo can be also exaggerated to far beyond the point where destructive clipping would occur with transformer-based designs for an even wider palette of saturation effects.

By manipulating these filters and harmonic generators; we can create two discrete Mojo styles; Thump and Cream. Both styles transform Camden 500 into the fattest, warmest, and most characterful preamp in your arsenal - all at the turn of a dial.

Test Drive Mojo For Yourself

Camden500_MOJO_CloseupYou supply the audio. We apply the Mojo. 

Hear the effects of our Mojo circuit on YOUR audio files by uploading a 30 second, WAV/AIFF (24-bit, 44.1/48kHz) audio file for us to reamp into Camden 500, apply the Mojo, and then send back to you - with no additional processing of course.

We’ll send the results back to you as a WAV file for you to analyse yourself, but we’d also like to post the results online so that others can hear the results for themselves. 

Before submitting, please make sure you are happy for us to post the file on our soundcloud playlist; we will apply any credits that you’d like - just let us know in the message section of the form below!
